AC Connections and UPS Start-Up
UPS Input / Output Power Overview
In order to achieve unity output, hardwire AC input to the UPS must be used. To achieve the maximum wattage output for
the models that are bundled with the SU6000XFMR2U transformer, its AC input must be hardwired as well. The chart below
describes power capacity for each bundled configuration utilizing corded or hardwired input and output connections.

*WARNING! Always use appropriate overcurrent protection in the output circuit of the transformer, as required by
National Electrical Code, ANSI/NFPA 70 and the Canadian Electrical Code, Part I, C22.1. Be sure to use branch-
rated circuit breakers that match the rating of the receptacles/equipment being protected.
